Le présent document complète la norme de base par des spécifications concernant les produits à base de polymère pour couronnes et ponts pour lesquels le fabricant revendique l'adhérence à l'infrastructure métallique sans rétention macromécanique, tels que tiges à bouton ou fils métalliques. Il ne s'applique ni au polymère de base d'une prothèse dentaire et à son adhérence aux alliages métalliques, ni aux systèmes métalIo-céramiques.
<p>ISO 10477:2004 classifies polymer-based dental crown and bridge materials and specifies their requirements. It also specifies the test methods to be used to determine compliance with these requirements. </p> <p>ISO 10477:2004 is applicable to polymer-based dental crown and bridge materials for laboratory-fabricated permanent facings or anterior crowns that may or may not be attached to a metal substructure. It also applies to polymer-based dental crown and bridge materials for which the manufacturer claims adhesion to the metal substructure without macromechanical retention such as beads or wires.</p> <p>ISO 10477:2004 is not applicable to polymer-based materials that are used to make crowns, veneers or repairs in the operatory, nor does it cover the application of those materials to stress-bearing areas of posterior teeth.</p>
